Claims.

The present invention relates to sole marking machines for use in themanufacture of shoes.

It has been found desirable in performing certain operations around thebottom margin of a 5 shoe such, for instance as the sole rounding oredge trimming operations on an outsole, and

particularly where these operations are performed by the use ofautomatic machines, to provide a templet located in proper position onthe 1 10 outsole, and to utilize this templet as a guiding means tocontrol or determine the outline on the shoe followed by the rounding ortrimming cutter. For the successful use of such a templet, it isnecessary that the templet be located in exact f l5 predeterminedposition with relation to the last contours of the shoe in order thatthe edge produced by the cutter may be used as a guide in subsequentoperations, as for instance the outseaming operation or that the edgeproduced by f the cutter or the outiine followed by an oper- 30 contoursof the shoe.

W ith this object in view the present invention contemplates theprovision with marking means adapted to form a templet positioningsurface on a shoe sole, of means for determining the relative positionsof said marking means and the shoe to cause a templet positioningsurface to be formed on the sole at a predetermined point with relationto the last contours of the shoe. Broadly considered, the inventioncontemplates the provision of any suitable means for marking the sole,but preferably this marking means consists of a marker adapted to forman indentation or prick mark on the sole. Also, in its broader aspects,the invention contemplates the provision of any suitable means by whichthe marking device and shoe can be readily and accurately brought into aposition to cause the indentation or other templet positioning surfaceto be formed at the desired point on the sole. In the constructionhereinafter described as embodying the invention, however, this resultis secured by means comprising gaging devices adapted to engage a lastcontour of the shoe, and position the shoe with relation to a relativelystationary marking device. i i

The templet in connection with which the marking machine is particularlydesigned to be used is located upon the shoe sole by means of a pin orprojection on the templet adapted to engage the indentation made by themarking device, so and also by means of a slot at its rear end adaptedto engage a pin projecting from the last through the inner and outersoles of the shoe. In the marking machine hereinafter described, thispin is also utilized in locating the shoe with relation to the marker, aguiding slot in a portion of the marking machine being provided toreceive the pin, and thereby cooperate with the gaging devices inlocating the shoe in the proper position with relation to the markingdevice.

The present invention also consists in certain devices, combinations,and arrangement of parts hereinafter described and claimed, theadvantages of which will be readily understood from the followingdescription taken in connection with the accompanying drawing, in whichFig. 1 is' a plan View of a marking machine embodying the severalfeatures of the present invention; Fig. 2 is a view in side elevationand partly in section of the parts shown in Fig. 1, a lasted shoe beingpositioned in the machine preparatory topricking the outsole; Fig. 3 isa sectional View in side elevation taken on the line 3-3 of Fig. 1, withthe parts shown in the position they occupy at the completion of solepricking operation; Fig. i is an underneath plan view of the markingmachine; and Fig. 5 is a plan view of the shoe after the prickingoperation.

Referring to the drawing, the frame of the marking machine illustratedtherein consists of a plate 6 extending upwardly and outwardly in aslightly inclined position from a boss 8 through which a bolt 10 passesby means of which the frame is rigidly secured to a suitable xed support12. The pricking pin for forming a templet positioning surface on theoutsole of a shoe is indicated at 14 and is mounted to reciprocate in aguideway formed in the plate 6. The lower end of this pin is pointed inorder to form an indentation in the shoe sole and the upper end of thepin is provided with a iiange 16 beneath 100 which a spring 18 islocated. This spring surrounds the pin 14 and is received in a recessformed in a boss projecting upwardly from the plate 6. The pin is thusnormally maintained 105 yieldingly in raised position by the spring.

The shoe to be marked is held by the operator with the tread surface ofthe sole uppermost and is resented to the marking devices with the toeportion or forepart of the shoe sole beneath the 110 plate 6, beinglocated in proper position by means hereinafter described.

For actuating the pin 14, to indent the shoe sole, an actuating lever isprovided which is pivotally mounted about midway its length between armsprojecting rearwardly from the plate 6. At its forward end, the lever 20is provided with a spherical or ball-like portion which engages a slotin the lower portion of the pin 14. The rear portion of the lever 20extends over the heel portion of the shoe which is presented to themarking device so that an upward movement of the heel portion or theshoe, after being located in proper position with relation to thepricking pin, actuates the pin to indent the sole.

To locate the shoe in proper position with relation to the sole prickingpin, gaging devices are provided to engage both the toe and heelportions of the shoe.

The gaging devices which operate at the toe portion or^ the shoecomprise an end gage 22 to contact with the last supported upper at theextreme toe end or" the shoe, and side gages 24 to contact with the shoeat each side of the toe portion. These gages contact with the lastsupported upper and thus locate the shoe and the surface of the outsolein predetermined position with relation to the last contour of the shoe.The gage 22 determines the longitudinal position of the shoe and isformed on a block 24 which is secured to the plate 6 so as to be capableof an adjustment longitudinally of the shoe by means of a bolt 26passing through a slot in the plate. The gages 24 act to position thetoe portion of the shoe laterally and are carried upon arms 28 pivotallymounted upon the plate 6. These arms are yieldlngly forced toward eachother by means of a connecting spring 30 and in order to cause the armsto move in unison toward and from each other so as to locate the toeportion o the shoe with relation to the indenting pin, their hubs areprovided with inter-meshing gear segments 32. The gages 24 are in theform of rolls and as the shoe is inserted into the machine these rollsextend beneath the projecting edge of the shoe sole and bear at theirupper ends against the under surface of the sole. A spring plate 34 issecured to the under surface of the plate 5 of the frame and at its rearend bears against the tread surface of the shoe sole adjacent the toeand acts to force the shoe yieldingly down into contact with the upperends of the rolls 24.

The gaging devices for the heel portion of the shoe comprise a slot 36formed in the rear end of the pin actuating lever 20 which slot isshaped to receive the head of a pin 38 projecting from the last of theshoe through the outsole of the shoe. This pin, in the constructionillustrated in the drawing, is a jig pin utilized in locating theoutsole in proper position on the shoe, as fully explained in the patentto George E. Warren, No. 1,706,504, dated March 26, 1929.

To mark the outsole of a shoe, the shoe is inserted in the machine sothat the forked portion of the lever 20 engages with the pin 38 and theshoe is advanced until the toe portion of the upper engages with theblock 22. At the same time, the toe is positioned laterally by theyielding engagement of the rolls 24 with the sides` of the shoe upper.After the shoe has been positioned in this manner, the heel is raisedsharply by the operator, thus causing the lever 20 to turn about itspivot and depress the marking pin 14 to indent the outsole, which issupported against the downward thrust of the pin by the gage rolls 24.
